Users are able to place planting that is automatically projected on to Topography or Floor, if these are available in the model. An option exists to place linear planting along the selected Model Line, which does not attempt to project on to a Topo of Floor if these have yet to be created.
Select either Flat 2D Line or Project on to Topography or Floor as required.
Note that if the underlying Topography or Floor has been modified since placing linear planting, converting to a Flat 2D Line and then converting back to Project on to Topography or Floor, will automatically force the linear planting to detect the new Topography or Floor.
